Pelco products with Wide Dynamic Range (WDR)
WDR or Wide Dynamic Range is used to even out a scene where part of it is bright and part of it is dark. This would be a scene such as looking into a warehouse door from the outside of a building. WDR evens out the bright and dark areas so you are able to see both areas.
